jerk on take off
On my 02 when ever I take off from a stop the truck has a jerk and it's starting to get to me now. It's only on take off and it shifts firmly into 4th often but other than that it feels fine. If I stomp on it from a take off it's like free spin for like 1/2 sec. then lock up and go. Any ideas on what it could be? TQ, U joints, diff., tranny or engine mounts, flywheel? The previous owners used it to pull his 11K 5th wheel around. The truck has 64K miles now and about 40K miles are pulling miles. I data logged my truck then data logged my moms truck which is the same truck but a 2000 and they both data logged the same. Both 4R100.
